Design and Fabrication of Thermoelectric Generator based on BiTe legs for Wearable Device Application |
| 초록 |
For the power supply of the wearable device, thermoelectric generator based on BiTe thermoelectric materials was designed, fabricated and characterized. The electrical properties of the n/p type BiTe thermoelectric materials was characterized by using ZEM-3 test set-up to measure Seebeck coefficient and electric conductivity. The thermal resistance of the thermoelectric generator was one of the important factors to select thermoelectric leg dimension, porosity, substrate size, etc. To apply the power generation with body heat, the thermal resistance was impedance matched with the measured human thermal resistance, such as, wrist. In this work, the designed module area size was 10X18 mm2 and the number of legs was 30 pairs. The expected power output voltage and power were several tens of mV and a few hundreds of uW under body heat condition. |
